Bought my first big bore, 505 Gibbs. Looking for load data/advice

I might try that load in my Sterling Davenport built 500J. I wanted to use the 600 Woodleighs mostly in that gun. Sounds like the perfect load if it's decently accurate. I will have to look into that flat nosed solid.

Double Tap ammo is loaded to 2200 with a 600 grain. I’ve seen data to about 2600.

I don't see 500J on Double Tap's page...505 Gibbs yes but not 500J?

May have dropped it, but I have a box o 10. Don’t know how old.
